ABSTRACT

This quantitative study aimed to identify the costs of the most frequent nursing activities in highly dependent hospitalized patients at a medical clinic. The non-probabilistic convenience sample corresponded to 607 observations regarding oral feeding activities (OF), blood pressure verification (BP) / heart rate (HR), body temperature checking (BTC), performance of intimate hygiene and management of feeding probe. The costs identified corresponded to R$2.40 (SD±2.64) for OF feeding; R$1.26 (SD±0.48) to verify the BP/HR; R$1.17 (SD±0.46) for BTC; R$15.59 (SD±8.62) to perform intimate hygiene and R$5.95 (SD±2.13) for management of feeding probe. This study will facilitate cost management, with a view to avoiding waste related to unnecessary resource consumption and establish a correlation between costs and care delivery results.

Introduction

According to the Brazilian Institute of Geography and Statistics, the hospitalization coefficient (number of hospitalizations divided by the number of inhabitants), the hospitalization rate (number of hospitalization days consumed per inhabitant and year) and the hospitalization cost rate (hospitalization cost consumed per inhabitant) of the Unified Health System are higher for the age range over 60 years than for any other age range in the Brazilian population. It is even observed that the hospitalization rate and the hospitalization cost rate increase progressively after that age and that the occurrence of rehospitalization among the elderly is five times higher than in the age range between 15 and 59 years(1).

It is estimated that 85% of the elderly suffer from at least one chronic disease, at least 10% of whom have five concomitant problems(2). In hospital contexts, it is observed that this association is directly related with the elderly's dependence level on nursing care.

It is highlighted that nurses who administer health units are responsible for human, material and physical resource management, demanding great financial resources. According to the institution's characteristics, nursing represents between 30 and 60% of the total staff. The volume of materials nurses manage at the different units is another important factor with regard to a health organization's costs. Thus, nurses have been pressured at their workplaces to reduce staff and material without, however, knowing the expense profile, relating it with care production and analyzing its costs(3).

This evidences the need for research on the costs of care delivery to hospitalized patients who are highly dependent on nursing and which permits knowledge on the costs of activities in these patients' care plan.

 

Aim

To identify the mean total direct cost (MTDC) of the most frequent activities for patients who are highly dependent on nursing care and hospitalized at the medical clinic.

 

Method

Study design

An exploratory and descriptive case study with quantitative data analysis was developed.

Place of study

The study was developed at the Medical Clinic (MC) of the University Hospital (UH) at the University of São Paulo (USP), as its human and structural resources contribute to the best practices in nursing care. The Unit offers 41 beds for care delivery to patients coming from the Adult Emergency Unit, Outpatient Clinic, Adult Intensive Care Unit and other hospital units.

The MC nurses offer the places for patient hospitalization and classify them according to the care type(4). During the research period, 14 beds were reserved for highly dependent and 29 for intermediate care patients. Each day, all hospitalized patients are assessed and classified and, when necessary, reorganized to the bed corresponding to their care profile.

In recent years, empirical evidence exists about the growth of the hospitalized elderly population at the MC. This population comprises chronic patients who are stable from a clinical viewpoint, but completely dependent on nursing actions to have their basic human needs attended to. According to these characteristics, the unit nurses classify them as Highly Dependent on Nursing (HDN) in Fugulin's Patient Classification System(4).

The profile of HDN patients mostly corresponds to elderly and/or chronic patients. They share the characteristic of total dependence for feeding, bathing, hygiene, mobilization and/or need constant surveillance, due to states of mental confusion or other neuro-cognitive alterations(5).

At the MC, the nurses manage the patients' care plan by means of the Nursing Process (NP), with a view to appropriate decision making on their care needs (diagnoses), what outcomes are intended (outcomes/targets) and what is the best care to see to those needs in view of the desired outcomes (interventions/activities)(6). To put in practice an intervention that helps the patient to achieve the desired outcome, they prescribe nursing activities, defined in the Nursing Interventions Classification(7) as specific actions or behaviors performed by nurses and, in the Brazilian reality, by nursing technicians and auxiliary nurses as well. The Unit has a nursing procedure manual to support the execution of the interventions, describing each recommended activity and distinguishing the standard materials needed for its accomplishment.

Ethical aspects

Data were collected after the research project received approval from the Research Ethics Committee and the institution's Research Ethics Committee (Registration Protocol N. 990/05 - SISNEP CAAE: 0018.0.198.196-10).

Cases/Sample

The cases corresponded to the opportunities to observe the activities nursing team professionals (nurses, nursing technicians and auxiliary nurses) accomplish most frequently for care delivery to HDN patients hospitalized at the MC, during morning and afternoon shifts, in July 2010 and January and February 2011, totaling 24 days. The months chosen and the number of days are justified by the fact that three nursing undergraduates with specific training performed the observations during holiday periods.

Initially, the identification of the accomplished activities was based on a recent study(5) at the Unit, in which HDN patients obtained the following basic activities as Nursing Activities Score(8) items: medication, except vasoactive drugs (100%); mobilization and positioning: accomplishment of the procedure more than thrice or involving two persons (95.95%); accomplishment of hygiene procedures taking less than two hours (90.07%); monitoring and controls: observation and/or continuous activity during two hours or more (84.58%); quantitative urinary output measure (71.11%) and treatment to improve the pulmonary function (51.50%). Then, these activities were complemented and detailed by consulting the nurses active at the MC.

Twenty-nine items were identified and, in those study, those activities will be presented that were performed most frequently during the study period. Hence, a non-probabilistic convenience sample was used, totaling 607 observations of five nursing activities: oral feeding activities (OF) (n=176), blood pressure (BP) / heart rate (HR) verification (n=114), body temperature checking (BTC) (n=114), performance of intimate hygiene (n=108) and management of feeding probe (n=95).

Data collection

To calculate the nursing activity costs, worksheets were elaborated to register the consumption of materials, the category and number of nursing professionals involved and the time spent to perform each activity.

Costs were verified using direct costing, defined as a monetary expense applied in the production of a product or service and which can be identified to the product or department. Direct cost is any cost that can be measured, i.e. identified and clearly quantified(9). At hospital units, these basically involve labor, material and equipment used directly in the care process(10).

Direct labor (DL) refers to the staff that works directly on a product or service delivery, provided that the time spent can be measured and the person who performed the work can be identified. It includes salaries, social charges, accrued vacation pay and thirteenth salary(9).

DL costs

The calculation of the DL unit cost was based on the mean salaries per professional category, as informed by the Financial Manager of the University Hospital-USP, based on the nursing staff working at the MC during the data collection period: nurse R$8,118.78; technician R$4,306.14 and auxiliary nurse R$5,553.53. At USP, no difference exists between the initial salaries for the nursing technician and auxiliary nurse categories. Therefore, since 2003, the Nursing Department (ND) at the hospital has only selected technicians, as these professionals have a more in-depth educational background than the auxiliary nurses. The auxiliary nurses working at the MC have been active at the institution longer and, therefore, their mean salary is higher, due to the benefits gained over the years.

As nursing professionals have a 36-hour weekly work journey at the hospital, DL costs corresponded to: nurse R$56.38 per hour and R$0.93 per minute; technician R$29.90 per hour and R$0.49 per minute and nursing auxiliary R$38.56 per hour and R$0.64 per minute.

Material and clothing costs

The Material, Warehouse and Equity Section of the hospital informed the material costs, complemented when necessary by the nurse responsible for material management at the ND. In this study, permanent equipment (digital blood pressure and cardiac frequency meters, stethoscope, digital thermometer and folding screen) costs at the MC were not surveyed, nor the cost of the enteral diet administration pump, as this equipment is on consignment.

Information on clothing costs was obtained from the Director of the hospital's Specialized Hygiene Service (SHS). Cost calculations were based on SHS professionals' estimate that each piece of clothing can be used 100 times at most. Processing costs per piece of clothing were added according to weight, considering that the institution pays R$1.77 per kilogram of clothing.

MTDC calculation

The MTDC of the most frequent nursing activities for HDN patients was calculated by multiplying the time the nursing professionals spent by the unit cost of DL and adding material costs. All calculations were elaborated in the Brazilian currency (R$).

Data analysis and treatment

The collected data were entered into electronic worksheets and submitted to pertinent statistical tests. The variables were subject to descriptive analysis through the observation of minimum and maximum values, calculation of means, standard deviations, medians and mode and displayed in tables. SPSS 15.0 for Windows e Excel were used for the calculations.

 

Results

The five most frequent activities were identified, related to interventions that involve direct care, i.e. treatments performed through interaction with the patient, which represent physiological nursing actions and comprise practical actions(6).

These nursing activities involving patients the nurses had classified as HDN totaled 607 observations and will be presented according to observation opportunity frequencies. The duration of each activity will be shown descriptively, some in minutes and others in seconds, as well as their MTDC, including staff, standard material as established in the ND nursing procedure manual and/or extra material consumption.

In Table 1, it is observed that the duration of the OF activity ranged between 1.00 and 21.00 minutes, with a mean 4.34 minutes (SD±4.09) and mode equal to 1.00.

Only staff cost was involved in this activity, varying between R$0.49 and R$18.60, with a MTDC of R$2.40 (SD±2.64) and R$ 0.49 as the most frequent amount.

The total accumulated staff cost for the 176 activities observed was R$86.24.

The analysis of Table 2 shows that the duration of BP/HR verification activities ranged between 60.00 and 320.00 seconds, with a mean 147.85 seconds (SD±52.61) and mode equaling 150.00. Only staff costs were involved in this activity, varying between R$0.49 and R$2.94, with an MTDC of R$ 1.26 (SD±0.48) and R$ 1.23 as the most frequent value.

The total accumulated staff cost for the 114 activities observed was R$143.64.

In Table 3, it is observed that the duration of BTC activities ranged between 40.00 and 420.00 seconds, with a mean 130.48 seconds (SD±55.03) and mode equaling 120.00. Staff costs varied between R$0.33 and R$3.43, with a mean R$ 1.10 (SD±0.44) and mode equal to R$0.98.

The MTDC related to the activity, involving staff and standard material costs (R$0.07), corresponded to R$1.17 and the most frequent amount was R$1.05.

The total accumulated staff cost for the 114 activities observed was R$133.38.

Table 4 shows that the duration of intimate hygiene activities ranged between 2.00 and 24.00 minutes, with a mean 7.81 minutes (SD±4.45) and mode equal to 5.00. Staff costs in this activity varied between R$0.98 and R$27.12, with a mean R$ 7.30 (SD±5.13) and mode of R$4.90. Standard material costs ranged between R$0.28 and R$25.53, with a mean R$5.57 (SD±4.52) and mode equal to R$2.87.

The following extra material was used: gown, long-sleeved protection apron, adult disposable diaper, mobile sheet, representing an additional R$2.72 in total activity costs.

The MTDC of the activity equaled R$15.59, with R$12.87 of staff and standard material costs and R$2.72 of extra material costs. The most frequent amount was R$8.27.

The total accumulated cost for the 108 activities observed was R$1,683.72, with R$788.40 (46.82%) spent on staff, R$601.56 (35.72%) on standard material and R$293.76 (17.23%) on extra material.

The analysis of Table 5 shows that the duration of feeding probe management activities ranged between 1.00 and 6.00 minutes, with a mean 3.13 minutes (SD±1.52) and mode equal to 2.00. Staff costs for this activity varied between R$0.49 and R$4.65, with a mean R$ 1.59 (SD±0.82) and mode equaling R$0.98. Standard material costs varied between R$0.00 and R$5.70, with a mean R$4.18 (SD±1.90) and mode equal to R$5.03.

The following extra material was used: medium procedure glove, representing an average additional cost of R$0.18 in total activity costs.

The MTDC for this activity totaled R$5.95, with R$5.77 related to staff and standard material costs and R$0.18 to extra material. The most frequent amount was R$6.99.

The total accumulated cost for the 95 activities observed was R$565.25, with R$151.05 (26.7%) spent on staff, R$397.10 (70.3%) on standard material and R$17.10 (3.0%) on extra material.

 

Discussion

During the study period, occupation rates at the MC corresponded to 87.9% in July 2010, 97.2% in January and 96.4% in February 2011, showing typical months at the unit, whose mean occupation rate exceeds 85.5%(11).

The most frequent activities observed involve some characteristics of patients classified in the HDN care category: stable vital signs (87.84%); bedridden (66.80%); oral feeding with nursing support (59.74%); eliminations in bed and/or use of urinary catheter for diuresis control (57.12%)(5).

At the MC unit, due to the HDN patients' profile, the nurses prescribe the verification of vital signs, although stable, at least thrice per day. For some of these patients, BP, HR, RF verification and BTC activities can be prescribed separately, at shorter intervals, with a view to attending to specific control needs.

In this study, activities related to indirect care interventions, performed distanced from the patients but in their benefit, which involve unit management and interdisciplinary cooperation actions(7), were not included in the cost verification. Therefore, it is highlighted that all direct and indirect care activities need to be identified in order to fully cover the costs of nursing care delivery to HDN patients.

The obtained results, however, can help the MC unit nurses to review the nursing procedure manual and adapt material consumption with a view to avoiding waste, in partnership with the nurses from the Educational Support Service.

Studies(12-14) evidence that, among different types of waste by nursing professionals and physicians, material-related waste is the most mentioned. It is highlighted that material resource management has aroused public and private health institution managers increasing concern, due to the high cost this has represented for these institutions(15).

Nurses correspond to an important decision level in resource allocation when they decide on service priorities at their work units and on what resources will be used to accomplish these. This is already the case at some private and public hospitals, where the nurse, as the manager of her business unit, assesses needs related to material, physical, human and financial resources; critical assesses unit expenses on a monthly base, comparing actual and budgeted expenses; and participates in budget planning for the upcoming year(16).

The global reality shows that health services are being confronted with a growing range of health needs and financial constraints, which limit investments in the sector's infrastructure and workforce(17) and can result in insufficient nursing staff to maintain the patient care security and quality(18).

The quality of the services a health institution delivers highly depends on its workers' technical competency and user interaction and communication skills, but also depends on other aspects, including ongoing work conditions and available material resources and support services(19).

It is obvious that, among the actions the nursing team performs, technical procedures entail risks and demand continuous assessment by the Nursing Services, with a view to guaranteeing the quality of the care process(20). Professionals also need to keep in mind, however, that care delivery has its costs, and knowing these costs can trigger reflections and discussions on the judicious and adequate use of the available, but not unlimited human and material resources.

In view of this panorama, cost management by nurses becomes fundamental with a view to decision making on efficient rationalization in the allocation of available and limited resources, with a view to achieving results that are coherent with clients' health needs and institutional needs/goals. Therefore, they need to understand a set of principles and know about economic analyses that permit choosing the most convenient decisions(21).

 

Conclusions

At the MC unit of the University Hospital affiliated with the University of São Paulo, 607 observations were made on 24 data collection days, during morning and afternoon shifts, related to OF, BP/HR verification, BTC, intimate hygiene and feeding probe management activities, which were identified as the most frequent during the study period.

The identified MTDC equaled R$ 2.40 (SD±2.64) for OF; R$ 1.26 (SD±0.48) for BP/HR verification; R$1.17 (SD±0.46) for BTC; R$ 15.59 (SD±8.62) for intimate hygiene and R$ 5.95 (SD±2.13) for feeding probe management.

The lack of similar studies that permit discussing the obtained results is considered a study limitation. Nevertheless, it will help the MC nurses with cost management, so as to avoid waste related to the unnecessary consumption of human and/or material resources, as well as to correlate cost measurement with the analysis of care delivery results. Identifying the MTDC of all nursing activities will enhance knowledge on the cost of direct and indirect care delivery to HDN patients and, in that perspective, this research will be continued.
