Assessment of the nursing staff's knowledge on periodontal disease and its associations with systemic changes

Avaliação do conhecimento da equipe de enfermagem sobre doença periodontal e suas associações com alterações sistêmicas

Abstract

Introduction

The maintenance of oral health in inpatients is essential, particularly to avoid complications arising from periodontal disease, which not only affect oral health but can also exacerbate systemic issues during hospitalization. Objective: This study aimed to assess nursing staff’s knowledge regarding the management of periodontal disease and its association with systemic diseases.

Material and method

This cross-sectional observational study was conducted in a general referral hospital of the Brazilian National Health System (SUS). A total of 504 nursing professionals completed a self-administered 24-item questionnaire on relating to oral care procedures and the importance of oral health in hospitalized patients. Data were analyzed using descriptive analysis and the chi-squared test (α = 0.05).

Result

Most respondents (97.8%) believed that oral infections can affect a patient's general health and that oral hygiene is important during hospitalization. However, knowledge deficits were identified. The oral effect of periodontal disease was considered moderate by 49.3% of the participants, and 74.6% believed that sugar was the most common cause of periodontal disease.

Conclusion

Nursing professionals are aware of the importance of maintaining oral hygiene and the relationship between periodontal and systemic diseases. However, their dental hygiene practice knowledge is limited. A training program on oral healthcare for inpatients and the inclusion of oral hygiene topics in the curricula of nursing professionals are recommended.

Resumo

Introdução

A manutenção da saúde bucal em pacientes internados é essencial, especialmente para evitar complicações decorrentes da doença periodontal, que não apenas afetam a saúde bucal, mas também podem agravar problemas sistêmicos durante a hospitalização. Objetivo: Este estudo teve como objetivo avaliar o conhecimento da equipe de enfermagem em relação ao manejo da doença periodontal e sua associação com doenças sistêmicas.

Material e método

Este estudo observacional transversal foi conduzido em um hospital geral de referência do Sistema Único de Saúde (SUS) do Brasil. Um total de 504 profissionais de enfermagem completaram um questionário autoaplicável com 24 questões, abordando procedimentos de cuidados bucais e a importância da saúde bucal em pacientes hospitalizados. Os dados foram analisados por meio de análise descritiva e teste qui-quadrado (α = 0,05).

Resultado

A maioria dos entrevistados (97,8%) acreditava que infecções bucais podem afetar a saúde geral do paciente e que a higiene bucal é importante durante a hospitalização. No entanto, foram identificados déficits de conhecimento. O efeito oral da doença periodontal foi considerado moderado por 49,3% dos participantes, e 74,6% acreditavam que o açúcar era a causa mais comum da doença periodontal.

Conclusão

Profissionais de enfermagem reconhecem a importância da manutenção da higiene bucal e a relação entre doença periodontal e doenças sistêmicas. No entanto, seu conhecimento prático em higiene bucal é limitado. Recomenda-se um programa de treinamento em cuidados bucais para pacientes internados e a inclusão de tópicos de higiene bucal nos currículos dos profissionais de enfermagem.

To the best of our knowledge, few studies on nursing staff knowledge of the importance of managing periodontal disease are available. Therefore, this study aimed to assess the knowledge of nursing staff (nurses, technicians, and nursing assistants) regarding periodontal disease, its association with systemic diseases, and the clinical management of patients with periodontal disease.

MATERIALS AND METHODS

Study Design and Ethical Issues

This cross-sectional observational explorative study was developed according to the ethical guidelines for human research and approved by the Ethics Committee on Human Research of the Federal University of Uberlândia, Brazil (CAAE:52673321.3.0000.5152).

Sampling, Context, and Study Participants

The study used a convenience sample of 504 nursing professionals (130 nurses, 286 nursing technicians, 87 nursing assistants) employed by the Public Clinical Hospital and Dental Hospital of the Federal University of Uberlândia, Brazil. The nursing staff work within a regional referral hospital of the Brazilian National Health System (SUS). A total of 526 questionnaires were completed between April 2022 and December 2022 by nursing professionals of both sexes, across all ages, and working in all shifts (morning, afternoon, and evening). However, 22 professionals (5%) were excluded because they did not disclose whether they were nurses, nursing technicians, or assistants. Nursing staff who refused to participate, and those on vacation or work leave were excluded from the study.

Data Collection Tool

The 24-item questionnaire was developed by a collaborative team that included dental professionals and nurses. The first part of the questionnaire identified the nursing team demography including professional categories, age, sex, income, and professional training experiences. The second part included questions relating to participation within a multidisciplinary team, interactions with dental professionals, knowledge on periodontal disease and its relationship with general health, oral care knowledge and practice routinely performed in the hospital environment, level of interest in receiving oral health-related information, and relevance to their work as nursing staff.

Data Collection

The participants were informed about the study. After written informed consent was obtained, one interviewer (ER) offered an anonymous, self-administered questionnaire. The questionnaire took approximately 30 min to complete. Questions from the participants were answered by the interviewer. For greater participant engagement, all inpatient departments of the Clinical Hospital were visited during the morning, afternoon, and evening shifts during nursing staff breaks (breaks for snacks, lunch, dinner, and overnight rest).

Data Analysis

Data were tested for normal distribution (Shapiro-Wilk test) and homogeneity of variance (Levene’s test), and a descriptive chi-square test was performed. Contingency coefficients were used to identify differences between nurses and nursing auxiliaries concerning socioeconomic variables and knowledge of oral health. All tests were performed using Jamovi Software (version 2.3.21), with a significance value of 5%.

Study Impact on Practice

At the end of the study, a comprehensive interdisciplinary training course on periodontal disease and inpatient oral healthcare was offered by dental professionals to interested nursing professionals. The training addressed patient management at hospitals, oral health education for the prevention of periodontal disease, and the use of hospital resources to assist in inpatient periodontal hygiene care. A standard protocol was also created to facilitate nursing professionals’ access to continued oral healthcare education.

RESULTS

Responses from the 504 nursing professionals who participated in this study are presented in Table 1. The study consisted of mostly females (380, 75.4%), with family income between levels 2 and 4 (221, 43.8%) of the minimum national wages. The mean age was 41.3 ± 10.0 years. There were no significant differences between nurses and auxiliary nursing staff.

Table 1
Analysis of socio-demographic characteristics of nursing staffs (nurses and nursing assistant team) included in the study

Approximately 66.5% of the respondents were able to identify normal gingiva. Nursing assistants reported higher knowledge of gum normality than graduated nurses (p < 0.05). Most participants (99.8%) reported that oral hygiene was important during hospitalization, and 98.6% reported that dental professionals should perform routine examinations for inpatients (Table 2). No significant difference was found between the graduate and auxiliary nursing staff (p = 0.861). Only 28% of the participants reported knowledge in toothbrushing techniques.

Table 2
Analysis of knowledge of nurses and nursing assistant team regarding patients' oral health

Staff responses regarding the effects of PD on general health demonstrated that the topic was not widely discussed, and their knowledge ranged between moderate (49.3%) to poor (31.1%). Additionally, 74.6% of the participants believed that sugar consumption was the most important etiological factor for PD. Knowledge of the influence of PD on systemic diseases was reported by 96.7% of participants. A significative percentage of respondents (88.9%) expressed an interest in specific training to deepen their knowledge about the impact of PD on the oral cavity and general health.

The participants’ answers to questions regarding inpatients’ oral hygiene instructions are shown in Table 3. It was found that 70.8% had never asked their inpatients whether they had been diagnosed with PD. Only 27.5% reported that they routinely instructed patients on the importance of maintaining oral hygiene during hospitalization. A moderate proportion of the participants (49.6%) had never or rarely (25.5%) instructed their patients about the general health consequences of PD.

DISCUSSION

The results of this study showed that most nursing professionals were aware of the systemic consequences of PD and had the knowledge that oral infections could harm patients’ general health. These findings are similar to the results in previous studies1616 Herrera D, Sanz M, Shapira L, Brotons C, Chapple I, Frese T, et al. Association between periodontal diseases and cardiovascular diseases, diabetes and respiratory diseases: Consensus report of the Joint Workshop by the European Federation of Periodontology (EFP) and the European arm of the World Organization of Family Doctors (WONCA Europe).

http://dx.doi.org/10.1111/jcpe.13807...
. However, patients were almost never instructed about the systemic effects of "diseased gums”.

Poor oral health directly affects the quality of life and overall health of hospitalized patients33 Cianetti S, Anderini P, Pagano S, Eusebi P, Orso M, Salvato R, et al. Oral health knowledge level of nursing staff working in semi-intensive heart failure units. J Multidiscip Healthc. 2020 Feb;13:165-73. http://dx.doi.org/10.2147/JMDH.S224453. PMid:32103976.
http://dx.doi.org/10.2147/JMDH.S224453...
. The host immune response to PD can trigger dysbiosis, resulting in the progressive loss of tooth-supporting tissues1616 Herrera D, Sanz M, Shapira L, Brotons C, Chapple I, Frese T, et al. Association between periodontal diseases and cardiovascular diseases, diabetes and respiratory diseases: Consensus report of the Joint Workshop by the European Federation of Periodontology (EFP) and the European arm of the World Organization of Family Doctors (WONCA Europe).

http://dx.doi.org/10.1111/jcpe.13807...
. Moreover, periodontal pathogens can directly or indirectly trigger the development of systemic diseases33 Cianetti S, Anderini P, Pagano S, Eusebi P, Orso M, Salvato R, et al. Oral health knowledge level of nursing staff working in semi-intensive heart failure units. J Multidiscip Healthc. 2020 Feb;13:165-73. http://dx.doi.org/10.2147/JMDH.S224453. PMid:32103976.

http://dx.doi.org/10.1016/j.bj.2018.12.0...
. The risk of oral pathogens entering the bloodstream is part of the intricate relationship between PD and chronic conditions, such as diabetes, cardiovascular disease, kidney disease, and respiratory problems1010 Sanz M, Marco Del Castillo A, Jepsen S, Gonzalez-Juanatey JR, D’Aiuto F, Bouchard P, et al. Periodontitis and cardiovascular diseases: Consensus report. J Clin Periodontol. 2020 Mar;47(3):268-88. http://dx.doi.org/10.1111/jcpe.13189. PMid:32011025.
http://dx.doi.org/10.1111/jcpe.13189...
. Additionally, the oral cavity structures, including the lips, tongue, mucosa, and gums, can serve as indicators of underlying systemic issues1717 Ahsan H. Biomolecules and biomarkers in oral cavity: bioassays and immunopathology. J Immunoassay Immunochem. 2019;40(1):52-69. http://dx.doi.org/10.1080/15321819.2018.1550423. PMid:30497330.
http://dx.doi.org/10.1080/15321819.2018....
.

It is valuable for the healthcare team to have knowledge and awareness of the systemic consequences of PD99 Taşdemir Z, Alkan BA. Knowledge of medical doctors in Turkey about the relationship between periodontal disease and systemic health. Braz Oral Res. 2015;29:55. http://dx.doi.org/10.1590/1807-3107BOR-2015.vol29.0055. PMid:25885023.
http://dx.doi.org/10.1590/1807-3107BOR-2...
. In this study, nurses' self-reported knowledge of the influence of PD on patients’ overall health was good. However, most had never applied this guidance to their patients.

The participants in this study reported the importance of oral hygiene during hospitalization. A similar result was found in a previous study that showed that nurses agreed that oral health should be a priority in patient care, although they found it difficult to maintain patients' oral hygiene1212 Saddki N, Mohamad Sani FE, Tin-Oo MM. Oral care for intubated patients: a survey of intensive care unit nurses. Nurs Crit Care. 2017 Mar;22(2):89-98. http://dx.doi.org/10.1111/nicc.12119. PMid:25349099.
http://dx.doi.org/10.1111/nicc.12119...
. This difficulty may be related to challenges with toothbrushing. Some participants in this study had no knowledge about toothbrushing techniques. As demonstrated by a previous nurses are not trained regarding the proper toothbrushing techniques for cleaning patients' teeth1414 Coker E, Ploeg J, Kaasalainen S, Carter N. Nurses’ oral hygiene care practices with hospitalised older adults in postacute settings. Int J Older People Nurs. 2017 Mar;12(1):e12124. http://dx.doi.org/10.1111/opn.12124. PMid:27353475.
http://dx.doi.org/10.1111/opn.12124...
.

Nursing care frequently uses technology to provide patient health support1818 Rantz MJ, Marek KD, Aud M, Tyrer HW, Skubic M, Demiris G, et al. A technology and nursing collaboration to help older adults age in place. Nurs Outlook. 2005 Jan-Feb;53(1):40-5. http://dx.doi.org/10.1016/j.outlook.2004.05.004. PMid:15761399.
http://dx.doi.org/10.1016/j.outlook.2004...
. In healthcare, technology is commonly understood as the use of high technology equipment1919 Barnard A. Philosophy of technology and nursing. Nurs Philos. 2002 Apr;3(1):15-26. http://dx.doi.org/10.1046/j.1466-769X.2002.00078.x.
http://dx.doi.org/10.1046/j.1466-769X.20...
. However, technology encompasses a range of professional skills, starting with soft technologies or interpersonal skills1919 Barnard A. Philosophy of technology and nursing. Nurs Philos. 2002 Apr;3(1):15-26. http://dx.doi.org/10.1046/j.1466-769X.2002.00078.x.

.

Knowledge of healthy gingival characteristics and possible pathological changes is important2222 Leite RS, Marlow NM, Fernandes JK, Hermayer K. Oral health and type 2 diabetes. Am J Med Sci. 2013 Apr;345(4):271-3. http://dx.doi.org/10.1097/MAJ.0b013e31828bdedf. PMid:23531957.
http://dx.doi.org/10.1097/MAJ.0b013e3182...
. Some participants demonstrated a lack of awareness regarding the normal gingival appearance. This may be a consequence of the lack of oral health content in the nursing curriculum11 Kim Y, Ku HM, Jun MK.

. The knowledge gap in oral health also resulted in most participants not asking whether their patients had previously been diagnosed with PD.

Knowledge of the potential risks of PD to the health of hospitalized patients makes it essential to conduct continued preventive evaluations in hospital2525 Duque AD, Malheiros Z, Stewart B, Romanelli HJ. Strategies for the prevention of periodontal disease and its impact on general health in Latin America. Section III: Prevention. Braz Oral Res. 2020 Apr 9;34(suppl 1):e025. https://doi.org/10.1590/1807-3107bor-2020.vol34.0025. PMid: 32294678.
https://doi.org/10.1590/1807-3107bor-202...
. It is important for nursing teams to have comprehensive knowledge on oral health and oral diseases1515 Gibney J, Wright C, Sharma A, Naganathan V. Nurses’ knowledge, attitudes, and current practice of daily oral hygiene care to patients on acute aged care wards in two Australian hospitals. Spec Care Dentist. 2015 Nov-Dec;35(6):285-93. http://dx.doi.org/10.1111/scd.12131. PMid:26297474.
http://dx.doi.org/10.1111/scd.12131...
. The present study demonstrated that the participants' knowledge of PD was rated as moderate or unsatisfactory.

Both participating groups, nurses and nursing assistants, believed that excessive sugar consumption was the primary causal factor of periodontal disease, which contradicts the scientific evidence2525 Duque AD, Malheiros Z, Stewart B, Romanelli HJ. Strategies for the prevention of periodontal disease and its impact on general health in Latin America. Section III: Prevention. Braz Oral Res. 2020 Apr 9;34(suppl 1):e025. https://doi.org/10.1590/1807-3107bor-2020.vol34.0025. PMid: 32294678.

. Moreover, sugar consumption is not a primary factor in the development of PD2626 Santonocito S, Giudice A, Polizzi A, Troiano G, Merlo EM, Sclafani R, et al.

http://dx.doi.org/10.3390/nu14122426...
. The nursing staff who participated in this study also misunderstood the etiologies of PD and caries, both of which are common in hospitalized patients2727 Đorđević V, Jovanović M, Miličić B, Stefanović V, Đukić-Dejanović S. Prevalence of dental caries in hospitalized patients with schizophrenia. Vojnosanit Pregl. 2016 Dec;73(12):1102-8. http://dx.doi.org/10.2298/VSP150917111D. PMid:29341566.
http://dx.doi.org/10.2298/VSP150917111D...
.

The importance of the presence of dental professionals in the inpatient monitoring team was an important finding in this study. This finding is consistent with the results of previous studies2828 Araújo RJ, Oliveira LC, Hanna LM, Corrêa AM, Carvalho LH, Alvares NC. Perceptions and actions of oral care performed by nursing teams in intensive care units. Rev Bras Ter Intensiva. 2009;21(1):38-44. http://dx.doi.org/10.1590/S0103-507X2009000100006. PMid:25303127.

http://dx.doi.org/10.1038/s41415-020-144...
. Nearly 86% of the nursing staff working in intensive care units in the city of Belém, Brazil, reported benefits of having dental professionals in the hospital teams2828 Araújo RJ, Oliveira LC, Hanna LM, Corrêa AM, Carvalho LH, Alvares NC.

http://dx.doi.org/10.1590/S0103-507X2009...
. However, most hospitals do not include dentists in their interdisciplinary teams2929 Hashem IW, Gillway D, Doshi M. Dental care pathways for adult inpatients in an acute hospital: a five-year service evaluation. Br Dent J. 2020 May;228(9):687-92. http://dx.doi.org/10.1038/s41415-020-1446-5. PMid:32385463.

The lack of knowledge and self-confidence of untrained nursing professionals results in inadequate patient management1313 Dagnew ZA, Abraham IA, Beraki GG, Mittler S, Achila OO, Tesfamariam EH.

http://dx.doi.org/10.1038/s41415-020-144...
. Most participants reported a desire for further training. Only a few participants answered differently, and this may be explained as perceiving oral hygiene practice for patients as unpleasant2323 Andrade-Leite DB, Martins-Santos SC, Marques-Gomes SM, Oliveira IJ. Knowledge, attitudes and practices of nurses regarding oral hygiene of dependent inpatients. Enferm Clin (Engl Ed). 2023 Jan-Feb;33(1):22-9. http://dx.doi.org/10.1016/j.enfcle.2022.05.003.

, and a lack of time to do it3030 Ghauri SK, Javaeed A, Chaudhry A, Khan AS, Mustafa KJ. Knowledge and attitudes of Pakistani intensive care unit nurses regarding oral care delivery to mechanically ventilated patients. J Pak Med Assoc. 2020 Jul;70(7):1203-8. http://dx.doi.org/10.5455/JPMA.5630. PMid:32799274.
http://dx.doi.org/10.5455/JPMA.5630...
. Awareness and training should be offered to nursing staff and updated continuously in the hospital environment22 Philip P, Villarosa A, Gopinath A, Elizabeth C, Norman G, George A.

http://dx.doi.org/10.1186/s12912-023-013...
.

This study has some limitations. The use of a convenience sample from a single teaching hospital limits the generalizability of the results. Additionally, the use of a self-administered questionnaire requires participant cooperation. Thus, there may have been a response bias due to favorable responses and data loss.

Strategies to overcome these issues may include comprehensive nursing training on oral care techniques for inpatients and hospital provision of all requisite materials and instruments for the optimal maintenance of patients' oral hygiene. Creating a dedicated daily schedule to guide and assist patients with oral hygiene practices and for assessing oral health as part of general health should also be considered.

CONCLUSION

Our study on nursing staff demonstrated a lack of knowledge regarding the presence, development, and prevention of periodontal disease. This may be due to a lack of specific training within nursing education. To address this, a well-structured training program with comprehensive guidelines on oral healthcare and hygiene of hospitalized patients should be considered in the nursing curriculum.
