Pneumococcal Vaccination in Nursing Homes: Does Policy Change Practice?

A Rising Tide Lifts "Related" Boats-Post-Acute Care Quality Improvement is Associated with Improvement in Long-Term Care Quality in Nursing Homes

OBJECTIVES

To examine the relationship between post-acute care (PAC) quality improvement and long-term care (LTC) quality changes.

DESIGN

Observational study using national nursing home data from Nursing Home Compare linked to Brown University's LTCFocus data.

SETTING AND PARTICIPANTS

Free-standing nursing homes serving PAC and LTC residents in the United States.

METHODS

This study used pooled cross-sectional analysis with nursing home-level data from 2005 to 2010 (12,150 unique nursing homes). We used fixed effects models to examine the association between a 1-year change in PAC quality and a 1-year change in LTC quality, with a specific focus on related care domains.

RESULTS

Strong and positive associations were found between related PAC and LTC care domains, particularly between the PAC and LTC influenza vaccination care domains (β = 0.30, P < .001) and the PAC and LTC pneumococcal vaccination care domains (β = 0.55, P < .001). Meanwhile, model results showed PAC quality changes essentially had no associations with unrelated LTC care domains.

CONCLUSIONS AND IMPLICATIONS

This is the first study that examines the association of changes in quality between 2 overlapping but different care domains (ie, PAC and LTC) using multiple quality measures. Our findings indicate that nursing homes can manage concurrent quality improvement in PAC and LTC, particularly on care domains that are related. More research is needed to examine the mechanism that enables such concurrent quality improvement.

Influenza Immunization in Nursing Homes: Who Does Not Get Immunized and Whose Status Is Unknown?

Objective.

To identify nursing home resident and facility characteristics associated with patients not receiving influenza immunization and having unknown immunization status.

Design.

Secondary data analysis using multinomial logistic regression of data from the National Nursing Home Survey, a nationally representative establishment-based survey.

Setting.

A total of 1,423 nursing facilities of all ownerships and certifications systematically sampled with probability proportional to number of beds.

Patients.

A total of 7,350 randomly sampled people aged 65 years or older residing in nursing homes between July and December 1999 (approximately 6 per facility).

Main Outcome Measure.

Immunization status of residents.

Results.

Fifteen percent of residents were not immunized and 19% had unknown immunization status. In multivariate analysis, lack of immunization and unknown immunization status were each separately associated with being newly admitted, with no or unknown pneumococcal immunization, and with facility failures to screen for immunization and to record inoculation in the medical record. High-risk status and staff immunization requirements had no effect. Separate analyses showed that residents with unknown immunization status are statistically significantly different from both those vaccinated and those not vaccinated.

Conclusion.

This study indicates that both resident and facility characteristics are associated with failure to be immunized for influenza. Facilities should consider targeting younger, newly admitted, and residential care residents for influenza immunization, since they are more likely to be missed. Further research into the barriers to immunization specific to nursing home resident choice or opportunity may be warranted.

Increasing influenza and pneumococcal immunization rates in a nursing home network

INTRODUCTION AND RATIONALE

Influenza and pneumonia remain serious health concerns for long-term care (LTC) residents. Vaccination of LTC residents and health care workers are reasonable preventive strategies, although most facilities fall short of Healthy People 2010 goals. Improving immunization rates across multiple LTC facilities remains an elusive challenge. This quality improvement study sought to improve immunization rates across 6 LTC facilities and identify persistent barriers to better performance.

METHODS

In 2002, 6 facilities associated with the University of Pittsburgh Institute on Aging established a quality improvement network addressing immunization rates. The facilities were provided with a written educational toolkit and shared information through an e-mail distribution list. To help determine optimal program structure in future years, 3 of the facilities participated in a single half-day collaborative training session. Change in immunization rates from baseline to year 2 were compared between those participating in the collaborative training and those not participating. Barriers to improved performance were sought from all groups through focus group analysis.

RESULTS

Facilities participating in the single collaborative training program improved immunization rates modestly, whereas facilities not participating in the collaborative training saw decreases in immunization rates. Staff turnover was cited as a significant barrier to improved performance.

DISCUSSION

It may be possible to improve immunization rates in LTC facilities, at least modestly, using a collaborative training process. Staff turnover may be an important barrier to improved LTC immunization rates.

Impact of NHAP guideline implementation intervention on staff and resident vaccination rates

OBJECTIVES

Determine whether a comprehensive approach to implementing national consensus guidelines for nursing home acquired pneumonia (NHAP), including influenza and pneumococcal vaccination, improves resident subject and staff vaccination rates.

METHODS

Quasi-experimental, mixed-methods multifaceted intervention trial conducted at 16 nursing homes (NHs) from 1 corporation (8 in metropolitan Denver, Colorado; 8 in Kansas and Missouri) during 3 influenza seasons, October to April 2004 to 2007. Residents with 2 or more signs and symptoms of systemic lower respiratory tract infection (LRTI) and NH staff and physicians were eligible. Subjects' NH records were reviewed for vaccination. Each director of nursing (DON) completed a questionnaire assessing staffing and the number of direct care staff vaccinated against influenza. DONs and study liaison nurses were interviewed after the intervention. Bivariate analysis compared vaccination outcomes and covariates between intervention and control homes, and risk-adjusted models were fit. Qualitative interview transcripts were analyzed using content coding.

RESULTS

No statistically significant relationship between the intervention and improved resident vaccination rates was found, so other factors associated with improved rates were explored. Estimated direct patient care staff vaccination rates were better during the baseline and improved more in the intervention NHs. Qualitative results suggested that facility-specific factors and national policy changes impacted vaccination rates.

CONCLUSIONS

External factors influence staff and resident vaccination rates, diluting the potential impact of a comprehensive program to improve care for NHAP on vaccination.

Association of standing-order policies with vaccination rates in dialysis clinics: a US-based cross-sectional study

BACKGROUND

Patients with end-stage renal disease are at increased risk of morbidity and mortality because of infection. Quality improvement efforts for this patient population include assessment of institutional policies and practices that may increase vaccination rates for influenza, hepatitis B, and pneumococcal disease.

STUDY DESIGN

A survey of vaccination practices, beliefs, and attitudes was sent to all dialysis centers in End-Stage Renal Disease Networks 6, 11, and 15.

SETTING & PARTICIPANTS

Of 1,052 dialysis facilities considered, 683 returned the survey, reported vaccination rates for 2005 to 2006, and had 20 or more patients.

PREDICTOR OR FACTOR

Standing-order policy of the dialysis facility, categorized as facility-wide orders, preprinted admission orders for each patient (chart orders), physician-specific orders, and individual orders.

OUTCOMES

Vaccination rates for influenza, hepatitis B (full or partial series), hepatitis B, and pneumococcal vaccine.

MEASUREMENTS

Patient vaccination, given at or outside the center.

RESULTS

Overall vaccination rates were 76% +/- 18% (SD) for influenza, 73% +/- 22% for hepatitis B full or partial series, 62% +/- 25% for hepatitis B full series, and 44% +/- 34% for pneumococcal vaccine. Compared with individual orders, facility-wide standing orders and chart orders were not associated with greater vaccination rates for influenza (0.4%; confidence interval, -4 to 5; and 1.27%; confidence interval, -3 to 5, respectively), but were associated with greater vaccination rates for hepatitis B full or partial series (9%; confidence interval, 3 to 15; and 11%; confidence interval, 5 to 17, respectively), hepatitis B full series (11%; confidence interval, 4 to 17; and 13%; confidence interval, 7 to 19, respectively), and pneumococcal disease (21%; confidence interval, 14 to 29; and 20%; confidence interval, 13 to 27, respectively).

LIMITATIONS

Data are cross-sectional, and vaccinations outside the center were self-reported.

CONCLUSIONS

Existing facility-wide or chart-based order programs may be effective in promoting vaccination against hepatitis B and pneumococcal disease.

Influenza and pneumococcal vaccine uptake among nursing home residents in Nottingham, England: a postal questionnaire survey

Background

Previous studies have shown influenza vaccine uptake in UK nursing home residents to be low. Very little information exists regarding the uptake of pneumococcal vaccine in this population. The formulation of policies relating to the vaccination of residents has been proposed as a simple step that may help improve vaccine uptake in care homes.

Methods

A postal questionnaire was sent to matrons of all care homes with nursing within the Greater Nottingham area in January 2006. Non respondents were followed up with up to 3 phone calls.

Results

30% (16/53) of respondents reported having a policy addressing influenza vaccination and 15% (8/53) had a policy addressing pneumococcal vaccination. Seasonal influenza vaccine coverage in care homes with a vaccination policy was 87% compared with 84% in care homes without a policy (p = 0.47). The uptake of pneumococcal vaccination was found to be low, particularly in care homes with no vaccination policy. Coverage was 60% and 32% in care homes with and without a vaccination policy respectively (p = 0.06). This result was found to be statistically significant on multivariate analysis (p = 0.03, R = 0.46)

Conclusion

The uptake of influenza vaccine among care home residents in the Nottingham region is relatively high, although pneumococcal vaccine uptake is low. This study shows that there is an association between pneumococcal vaccine uptake and the existence of a vaccination policy in care homes, and highlights that few care homes have vaccination policies in place.

Overview of vaccination in chronic kidney disease

Infections are a major cause of death in end-stage renal disease (ESRD) patients, second only to cardiovascular disease, and also contribute to significant morbidity in patients with earlier stages of chronic kidney disease (CKD). Vaccines are a strategy to attempt to reduce morbidity related to infections. Patients with CKD and ESRD may not respond as well to vaccines as patients without kidney failure, but adequate seroresponse with standard or augmented regimens for vaccinations against influenza, hepatitis B, pneumococcus, and varicella have been documented. Influenza, in particular, seems to provide adequate protection with standard dosing regimens. Despite somewhat reduced effectiveness of certain vaccines in patients with CKD, there is emerging evidence of benefit to vaccination in these populations. However, vaccination rates are relatively low. Given the accumulating evidence of benefit, continuing quality improvement programs focused on increasing vaccination rates in patients with all levels of CKD are needed.
