Smoking is associated with ≥ 50% increased risk of developing pneumococcal disease.[a] Asthmatics have at least a 2-fold higher risk for pneumococcal disease.[b] Streptococcus pneumoniae is1 of 3 core pathogens exacerbating COPD and chronic bronchitis.[c] Respiratory Comorbidities a.

Many comorbidities could be recognized by a GP or nurse. UK NHS has warning system —yellow flag attached to notes of patients with comorbidities Nurses and GPs have a duty to recognize the significance of chronic conditions and importance of pneumococcal vaccination. Patients also need to be educated so they know they are at risk. Are GPs Aware of Risks for Pneumococcal Disease? NHS = National Health Service

Very little data on incidence as most people are treated as outpatients with no microbiological diagnosis; bacteriological tests not very sensitive[a] United States—annual incidence of IPD or nonbacteremic pneumococcal pneumonia in adults ≥50 years:5.8 per 1000[b] Spain—annual hospitalization rate for pneumococcal pneumonia in adults > 50 years: 1.09 per 1000[c] Incidence of Pneumococcal Disease in Older Adults a.

Pneumococcal infections are prevalent. Associated with significant morbidity and mortality, particularly in older patients and those with comorbidities Delaying treatment or using an ineffective therapy is associated with higher morbidity and mortality. Pneumococcal infections are associated with decreases in quality of life. Better to prevent pneumococcal infection than identify and treat it Pneumococcal Disease: Key Points
PPV Immunization Rates in Primary Care • Immunization rates rising in England: > 70% of people aged > 65 years in 2011 • Rates were much lower in those < 65 years in clinical risk groups. • Need to promote vaccination to at-risk patients PPV = pneumococcal polysaccharide vaccine UK Department of Health. Pneumococcal Polysaccharide Vaccine (PPV) Uptake Report; 2012.

Barriers to Pneumococcal Immunization • Lack of government commitment • Lack of a national media campaign • Lack of physician/nurse endorsement • Lack of vaccine reimbursement • Level of physician fee • Fear of adverse reactions • Fear of injections Burns IT, et al. J Fam Pract. 2005;54(Suppl 1):S58-S62. Rehm SJ, et al. Postgrad Med. 2010;124(3):71-79.
Barriers to Pneumococcal Immunization (cont) • Perception that “vaccination is for children” • Confusion with influenza vaccine • Not aware of the benefits • Individual not made aware he/she is in a group at risk • Professional apathy to vaccination Burns IT, et al. J Fam Pract. 2005;54(Suppl 1):S58-S62. Rehm SJ, et al. Postgrad Med. 2010;124(3):71-79.
How Can We Increase Pneumococcal Immunization Rates in Primary Care? • Encourage patients to make an appointment • Invite by letter, telephone, or text message • Invite when they contact the clinic in person or by phone • Target specific groups (eg, > 65 years) • Don’t forget the house bound • Vaccinate during the annual influenza campaign Willis BC, et al. MMWR Recomm Rep. 2005;54(RR-5):1-11.
How Can We Increase Pneumococcal Immunization Rates in Primary Care? (cont) • Opportunistic • During any nurse or doctor consultation • While they are waiting at the clinic to see a doctor or nurse • When they collect a repeat prescription • When they bring a relative to the clinic • While at the clinic for cervical cytology, family planning, diabetes, COPD clinic, etc. Willis BC, et al. MMWR Recomm Rep. 2005;54(RR-5):1-11.
Conclusions • Pneumococcal disease is associated with considerable mortality and morbidity. • Pneumococcal disease is best managed by prevention through vaccination rather than treating it once the disease has occurred.
